Found this video on loading of auto racks. When I pictured the loading of these, I figured they did them one at a time. I had no idea they drove through all the cars. Anyway I thought it was neat , and I learned something.
Every once in a while a driver will crash one of the cars.
I used to drive the new 1973 Thunder Birds, Mark IIIs and Lincolns out of the Wixom, MI plant and park them for loading onto carriers.
